det(\left(\begin{matrix}3&-2&1\\5&3&0\\1&1&-2\end{matrix}\right))

Diagonal usulidan foydalanib matritsaning aniqlovchisini topish.

\left(\begin{matrix}3&-2&1&3&-2\\5&3&0&5&3\\1&1&-2&1&1\end{matrix}\right)

Birinchi ikki ustunni to'rtinchi va beshinchi ustun sifatida qaytarish uchun asl matritsani kengaytirish.

3\times 3\left(-2\right)+5=-13

Pastki chap kiritmadan boshlab diagonal kamayish tarafga ko'paytirish ha koʻpaytmalarni qo'shish.

3-2\times 5\left(-2\right)=23

Pastki chap kiritmadan boshlab diagonal ko'payish tarafga koʻpaytirish va koʻpaytmalarni qoʻshish.

-13-23

-13 dan 23 ni ayirish.

det(\left(\begin{matrix}3&-2&1\\5&3&0\\1&1&-2\end{matrix}\right))

Kichik a'zolarni kengaytirish usulidan foydalanib matritsaning aniqlovchisini topish (ko'paytiruvchilarni kengaytirish deb ham nomlanadi).

3det(\left(\begin{matrix}3&0\\1&-2\end{matrix}\right))-\left(-2det(\left(\begin{matrix}5&0\\1&-2\end{matrix}\right))\right)+det(\left(\begin{matrix}5&3\\1&1\end{matrix}\right))

Kichik a’zolarga kengaytirish uchun birinchi satrning har bir elementini o‘zining kichik a’zosiga ko‘paytiring, qaysiki ana shu elementga ega bo‘lgan satr va ustunni yo‘q qilish orqali yaratilgan 2\times 2 matritsasining maxraji hisoblanadi, so‘ngra elementning joylashuv belgisiga ko‘paytiring.

3\times 3\left(-2\right)-\left(-2\times 5\left(-2\right)\right)+5-3

2\times 2 matritsasi uchun \left(\begin{matrix}a&b\\c&d\end{matrix}\right), maxraj ad-bc.

3\left(-6\right)-\left(-2\left(-10\right)\right)+2

Qisqartirish.
